When creating your license plate you can get a bunch of different features to customize your plates such as handicap signs and many more. Simply hold L1 and R1 and press LEFT or RIGHT on the D-pad to cycle through the options (you can place these signs anywhere in your plate).

To unlock the bonus movie, get all 3 endings (poor, average, and best) by successfully passing all of the episodes, including the alternate ones. This extra movie is just for fun, and it shows Masterson and Nick doing something silly at the Gulag Club.

You can simply shoot obstacles on the driving courses to get rid of them. This does not count as something you hit, and it will make several of these courses (especially the Two-Wheel course) very easy to beat.

On the map screen, press R1, L1, UP, RIGHT, LEFT, DOWN, L3, R3, X, SQUARE, CIRCLE, TRIANGLE. You should hear a chime to confirm that you did it correctly. Now, go to a place that will save your game. Now, go to the Mission Select Screen and pick a mission that shows Snoop's head to play as him.

This is an easy way to get money. While you are walking down the street, go up to any person and press circle. You will frisk them, if they are clean, you let them go, but if they have any drugs, you get bonus money. What fun!
